Wickes metal doors

Wickes have said they are only weatherproof from one side so they cannot be fitted back to front. Thinking about it, most people I know have internally opening doors. I presume that is to stop the wind slamming them shut. Do outward opening doors exist?

It is easier to design a door to open outwards as far as the weatherproofing goes, in fact its hard to see how a door could not be such from the open-toward-you side given the rebates etc. I guess around hinges may be an issue. T'would be interesting to look at these doors. Front doors are usually open inwards, but often sheltered under an arch etc. Back doors often open outwards. I have an open outwards door fitted back to front at the moment but it is sheltered and in a temporary plywood wall anyway. Weather proofing has to rely totally on any seals rather than an overhang.
